Supporting device

Abstract

A supporting device including an upright, a diverting member, a connecting element, a holder, and an adjustable counter-weight module is provided. The diverting member is disposed on the upright, the connecting element is partially disposed around the diverting member, the holder is slidably disposed on the upright and connected to the connecting element, and the holder is to support the display. The adjustable counter-weight module is connected to the connecting element, and includes a plurality of counter-weight units. When an external force is applied to move the display relative to the upright, the connecting element drives the counter-weight units connected to the connecting element to move simultaneously. When the external force is removed, the display stops relative to the upright.

What is claimed is: 
     
         1 . A supporting device for supporting a display, the supporting device comprising:
 an upright;   a diverting member, being disposed on the upright;   a connecting element, being partially disposed around the diverting member;   a holder, being slidably disposed on the upright, connecting to the connecting element, and supporting the display; and   an adjustable counter-weight module, being connected to the connecting element and including a plurality of counter-weight units, wherein the display, the holder, and the adjustable counter-weight module are in a static balancing state through a presetting number of the counter-weight units moving along with the connecting element;   wherein the display is able to move relative to the upright and leads the connecting element to drive the counter-weight units to move simultaneously when an external force is applied to the display, and the display is stopped relative to the upright at any position when the external force is removed.   
     
     
         2 . The supporting device of  claim 1 , wherein the adjustable counter-weight module further includes a weight bearing element connected to the connecting element, wherein the connecting element leads the weight bearing element to move down or up, and at least one of the counter-weight units moves down or up along with the weight bearing element when the display moves up or down relative to the upright. 
     
     
         3 . The supporting device of  claim 2 , wherein the adjustable counter-weight module further includes a pin, the counter-weight units are disposed stacked, each of the counter-weight units has a first hole and a second hole, and the pin is adapted to selectively insert into the second hole of any one of the counter-weight units. 
     
     
         4 . The supporting device of  claim 3 , wherein the adjustable counter-weight module further includes a housing, wherein the counter-weight units are disposed therein. 
     
     
         5 . The supporting device of  claim 4 , wherein the weight bearing element includes a plurality of third holes and passes through the first holes of the counter-weight units along a first axis, and the second holes correspond to the third holes for the pin penetrating through a through groove of the housing to insert in one of the second holes, so that while the external force is driving the display and the holder to move up or down relative to the upright, the connecting member leads the weight bearing element to move down or up, and simultaneously drives the counter-weight units between one end of the weight bearing element and the pin to move down or up. 
     
     
         6 . The supporting device of  claim 4 , wherein the upright includes a first sliding groove and a second sliding groove, and the holder includes a first sliding element, wherein a plurality of first friction elements of the first sliding element and a plurality of second friction elements of the weight bearing element are respectively disposed in the first sliding groove and the second groove, the weight bearing element is connected to the connecting element and disposed between the upright and the housing, and when the holder is moving relative to the upright, the first friction elements slide in the first sliding groove and the second friction elements slide in the second sliding groove. 
     
     
         7 . The supporting device of  claim 6 , wherein the housing includes a first through groove and a second through groove corresponding to the first through groove, and the weight bearing element further includes a fourth hole, wherein the pin sequentially penetrates the first through groove, one of the second holes, the second through groove and the fourth hole, and while the holder is moving up or down relative to the upright, the connecting member drives the weight bearing element to move down or up, and the counter-weight units above the pin move up or down simultaneously. 
     
     
         8 . The supporting device of  claim 7 , wherein the adjustable counter-weight module includes a positioning rod for the counter-weight units to be sleeved thereto, and the counter-weight units are adapted to move up or down with respect to the positioning rod. 
     
     
         9 . The supporting device of  claim 1 , wherein the connecting element has a first end and a second end corresponding to the first end, wherein the holder is connected to the first end, and the adjustable counter-weight module is connected to the second end when the connecting element is partially disposed around the diverting member. 
     
     
         10 . The supporting device of  claim 1 , wherein the diverting member is a fixed pulley structure.
